2.5 Installation procedure

2.5.1 Connecting C.O. lines & extensions to the unit:
1. Please connect the monomer-crystal with EXT. line and C.O. line separately;
2. Make sure to avoid short circuit.
3. Connecting extensions according to the in-dilated extension positions and C.O. lines to the corresponding line
ports on the unit.

2.5.2 Zero-load power-on inspection:

1. The operation voltage of this product is AC220V or AC110V. Check out the voltage of local power supply. A UPS
backup is highly recommended.
2. Plug in the power supply line, indicating normal power supply and working state of the machine.
3. Pick up the handset of extension 11. A sharper internal dial tone indicates that the system is working normally. You
can start to setup operation now.

2.6 Direct Access when Power Failure

The C.O. lines will be connected direct to the special Exts automatically when the power failure. The No.1 C.O.
line will be connected to Ext. 11 and No.2 to Ext.12, No.3 to Ext.13, So you only can use the Three Exts as normal
phone with direct C.O. line
cannot be connected directly when there is power failure.)
For example when someone call in with No.1 C.O. line at the time of power failure, the Ext.11 will ring, you can
only pick up Ext. 11 and talk with the caller.
(206: Only No.1 C.O. line can be connected to Ext.11 directly, i.e. No.2 C.O. line
